ENGINE
To Whom It May Concern, I am writing to express my concern regarding my 2014 Hyundai Sonata, Vehicle Identification Number (VIN): [XXX] , which is currently experiencing excessive oil consumption. I have recently become aware of Recall Campaign 162, which addresses a manufacturing defect that can lead to premature engine wear and related issues. Despite regular maintenance and proper care, my vehicle consumes an abnormal amount of oil, causing me to frequently top off the oil between oil changes. This not only increases my maintenance costs but also raises serious concerns about the safety and reliability of my vehicle. **A trusted service provider has confirmed that the oil consumption in my vehicle is abnormal and is likely related to the defects outlined in Recall Campaign 162.** As stated in the recall, the machining errors during the engine manufacturing process can restrict oil flow to the bearings, leading to premature bearing wear. Although my vehicle does not currently exhibit any visible oil leaks, the oil consumption issue suggests underlying damage that could potentially lead to engine failure. Considering the potential risks and the known issues with the Theta II engine, I kindly request that my vehicle be inspected and, if necessary, repaired under the terms of Recall Campaign 162. I urge you to address this matter promptly to ensure the safety and reliability of my vehicle. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ENGINE, UNKNOWN OR OTHER
The vehicle suddenly spiked in RPMs, and suffered from a rattling noise. The following day after taking it to a known skilled service location, they advised to contact the dealership due to two open recalls. They found zero oil in the vehicle as well as issues with the valve seals. They then put the blame on the customer and did not acknowledge the engine recall that states clear problems with oil and engine valves resulting in a loss of oil and a failure in monitoring systems. At no time did the oil light show on the dash and there was no oil in the driveway where the vehicle has been parked. They advised us to contact the company for assistance. After doing so, the dealership, and Hyundai themselves have refused to acknowledge the engine issues or repair the car under the two known open recalls. We have spoke with reps from both the dealership and the company an have received no assistance in reclaiming confidence in the vehicle or Hyundai as a whole. This happened in September 2024 and there is no resolution in sight here in December. How a customer can be expected to repair at their own cost during a known recall with a class action lawsuit is ludicrous.

I was driving and my car started beeping and the wheel jerked to the left and my car slowed down from 65mph to 20mph and almost caused me to have an accident. After I replaced the breaking module, my battery started shorting out and my car once again jerked off to the side and then slowed down abruptly from 65 mph to 20mph.

ENGINE
The contact owns a 2014 Hyundai Sonata. The contact stated that while driving approximately 70 MPH, the vehicle suddenly lost power and the contact was able to coast to the side of the road. The instrument panel was illuminated with several unknown warning lights. The contact restarted the vehicle and continued driving. Three months later, on November 11th, 2024, while driving approximately 40 - 45 MPH, the check engine warning light illuminated with a message indicating a failure with the Variable Valve Timing Solenoid. An independent mechanic confirmed that the Variable Valve Timing Solenoid was the cause of the failure, and the contact replaced the part himself. The following day after being idle at a stop light, the contact attempted to accelerate, and the vehicle failed to accelerate. The vehicle was restarted; however, there was a knocking sound coming from the engine compartment. The contact had the vehicle towed to the residence. The contact used an OBD machine to diagnose the vehicle and retrieved fault codes for an oil pressure failure which caused the engine failure. The vehicle had not been taken to the dealer to be diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was 120,326.

EXTERIOR LIGHTING
The turn signal stem assembly randomly begins failing after several years (approx 5 years). Issues will be noticed while driving in the dark. When turn signal is applied in both directions, occasionally headlights will turn off or flash causing interior lighting to change to brighter daylight settings at the same time. This can be disorienting for the driver as well as others on the road. To remedy the incorrect lighting situation, the driver needs to jiggle the turn signal stem assembly and normal lighting will resume. At subsequent turns, the entire situation repeats itself. Other drivers may believe they are being alerted to something or potentially angered, causing misunderstandings or altercations on the road. My original turn signal stem assembly was replaced after about 5 years due to this series of events. Now, after approximately 5 more years, the exact same symptoms have begun again with the authentic Hyundai OEM replacement parts.

The entire dashboard is cracking and has caused the airbag light warning light to come on, due to the compromised dashboard. This makes me feel unsafe because I'm not sure if the airbag will launch prematurely. I see online that many Hyundai owners have experienced this same issue and have the same concerns.

EXTERIOR LIGHTING, ELECTRICAL SYSTEM
Electrical system going out only at night because headlights and inside lights are turning off for a few seconds only while driving at night this has happened multiple times since august and is becoming a safety concern while driving at night it's a safety concern because this has happened incoming traffic on roads and highways. The vehicle hasn't been inspected by dealership I tried calling to get an appointment but was told there is a fee and if something electrical a may have a cost per hour to inspect. No warning lights are turning on prior to headlights and inside lights going out. During the day no issues with vehicle. I've read a few online posts from other owners with same issue.

ENGINE, POWER TRAIN
I was driving at a higher rate of speed 50 MPH in the center of 3 laned road no warning or indicator lights were on in my vehicle when the engine without warning blew and stopped working. Again no check engine lights were on no warnings were given. It shut down and would no longer accelerate or drive. We almost caused several accidents as this was a very busy roadway.

STRUCTURE:BODY
My passenger side rear door will not open from the outside or the inside. You pull the handle on the outside and nothing happens. You push the door from the inside and nothing even budges (the door lock still works not that there's a use for it right now). This seems to me to be a safety risk for anyone that has to sit in the backseat behind the front passenger seat. If there were an emergency, they would not be able to open the door to get out. I have Googled this and it seems to happen quite frequently in Hyundai cars. It's the door actuator. If this happens a lot, then I think Hyundai needs to take a deeper look into their door actuators. Thank goodness I do not have kids in a car seat because I would be unable to get them in or out on that side of the car. I've never had this happen on any of the Toyotas I've owned.

Extremely rough idle when stopped. Trying to accelerate to merge into traffic the my. Car had no power and I almost got creamed ! I had to pull over so other cars could go around me. Several other issues with car like oil every month or so. I had gas pouring from a hose on my engine and when I brought it to dealership they wanted 1100.00 knowing it was a recall. I hope the dealership and Hyundai rot. !

I was driving at approx 30mph and all of a sudden I get a warning on my dashboard that says "Hybrid System Warning - Check brakes- safely stop and do not drive". My car slowed down and the brakes went to the floor. I was able to coast it to the side and turn off my car. I waited a few minutes, turned it back on and it was fine. The same thing happened 3 months ago. I took it to the dealer the first time it happened and they replaced the 12v battery and cleared all the codes. They couldn't find out exactly what was wrong. Suggestion was if it continues, then replace the hydraulic module for over $5k. It did happen again, but didn't take it to the dealer, but to a local mechanic. They checked the brakes and are fine. The codes were the same and said it might be the Hydraulic Booster High Pressure Accumulator (HPA). I was reading the Hyundai forum and this seems to happen to many Hyundai hybrids. I'm concerned for my safety and the safety of others if I was driving on the freeway and the same thing happens. There's no advance warning. I could cause an accident because of it. Seems that Hyundai needs to issue a recall on the hydraulic module and replace it.

SERVICE BRAKES
ABS control unit/pump is leaking. I was told it's not covered under warranty or recall. Local mechanic states they can't repair it because the part has to be properly programed at the dealership. I've spoken with other Hyundai owners and they have had the same issue.

ENGINE
Stopped at a stop light, started going again, got up to about 20 mph and engine stalled on the side of the road. Had to wait HOURS for a tow, triple A couldn’t help, had to pay $70 out of pocket. Now they are denying me for an engine replacement, each time I submit the documentation they request, they find some reason to turn it down, and when I ask what they specifically needed me to do, they just gave me a phone number to call for Hyundai customer affairs, even though I have already gone through all of this with them, and they directed me back to the dealership as far as communication goes. I’m getting the run around, and it has been going on since May.

Car stalled at 65 mph and went in to limp mode. Knocking noise came from under right side of engine. Car is not drivable at this time. Sounds like a rod thrown and there are metal shaving in oil.

FUEL/PROPULSION SYSTEM
NHTSA recall 22V312000 Not implemented by Jerry's Hyundai My vehicle has been at Jerrys Hyundai since Feb 15th 2023 due to a failed engine. I verbally asked to have the recalls done once the engine was replaced and also asked if the recalls were complete before picking up the vehicle. I was told all the recalls would be done once the car was running and I was also told that the recalls have been done. I have scheduled the recall service twice now the first being the end of June 2024. The 2nd one being for July 1st 2024 and I am not getting any response to phone calls, emails etc.
